A bus company charges $30 per person for a sightseeing trip if 28 people are in the group. For each additional 2 people, they drop the price $1. How many people will maximize the revenue for the bus company.
8 additional people will maximize the revenue. Total number of people will be (28+2x) = (28+2(8)) = (28+16) = 44 people.
